AUTOMATIC DAM PER -REGULATOR.

SPECIFICATION forming part of Letters Patent No. 335,662, dated February 9, 1886.

Application filed May 15,1885. Serial No. 165,609. (No model.)

To all whom it mayconcern:

Be it known that I, SoLoMoN WEINBERG, a citizen of the United States, residing in N ewark, Essex county, New Jersey, have invented certain new and useful Improvements in Au tomatic Damper-Regulators, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

This invention relates to that class of damp- .er-regulators in which a clock-work is connected with the damper in such manner as to open or close the latter at a predetermined time; and my improvements consist, first, in I 5 combining with the clock-movement an auxiliary train having a cord-pulley applied to the springspindle, and having a wheel, to the teeth of which a pawl is applied and regulated by a connection to a notched disk upon the hour-spindle of the clock-movement, so

that the cord-pulley may be rotated continuously with the entire force of the auxiliary train at a predetermined time.

It also consists in the combination, with the damper, of an. actuating-spring and a handconnection, whereby the spring may be placed under tension, the connection being provided with a lock, so that it may be secured with the damper in a given position and in readiness for the spring to actuate the damper when the connection is unlocked.

It also consists in a connection between the pulley upon the auxiliary train and the look-- ing device, whereby the rotation of the pulley 3 5 releases the bolt and permits the damperspring to operate the hand-connection.

, My improvements are shown in the annexed drawings, in which Figure 1 is a front view of the clock-movement, the cord-pulley, the

hand-connection to the damper, and the looking device therefor. Fig. 2 is a diagram showing a furnace, the hand-connection adjacent thereto, and a bell-crank, spring, and cord for actuating the sliding damper and uniting the .1, 5 same to the hand-connection, the latter being shown in Fig. 2 in a line with the connection in Fig. l, to indicate the co-operation of the parts shown in the two figures. Fig. 3 is an edge view of the clock-movement, the parts being largely omitted that do not actuate the pulley-train; and Fig. at is a diagram showing the application of the hand-connection di rectly to a hinged damper.

A is the frame of the clock-movement; B, the hour-dial; O, the hour-hand; D, the minute-hand; E, an indicator affixed movably upon the hour-spindle, and F the notched disk attached to the indicator and rotating by frictional contact with the hour-spindle. The spring and train of wheels for driving the hourspindle are not shown, as their construction is well understood.

In the pulley-train, a is the pulley-spindle; b, the spring; 0, its ratchet; d, the pulley, and e a spur-wheel turning loosely on the spindle and provided with the detent c. The wheel 6 meshes with a small wheel, f, upon a shaft, g, to which the stop-wheel h is affixed.

i is the pawl mounted on arm j, and applied to the teeth of the stop-wheel h. r

k is a lever having a tooth, Z, fitted to th notch n in the disk F, and m is a link connecting the arm j and lever 70, the parts being so proportioned that when the tooth Z rests upon the rim of the disk F the pawl t is held into the teeth of the stop-wheel and the pulleytrain is locked.

The circular indicator E,like that commonly used in alarm-clocks, serves to set the notch in the disk so that the tooth Z may fall into the notch at any predetermined time, thus releasing the stop-wheel h and unlocking the pulley-train. A cord, 1), is attached to and winds around the pulley d,and when the stopwheel is locked the spring I) may be wound up by pulling the cord and rotating the pulley and ratchet,while the latter slips past the detent pinned on the wheel 6.

G represents a heating-furnace placed beneath the floor G; 1', a sliding damper for supplying air beneath the grate; r, a cord or chain attached thereto and to the arm 8 of a bell-crank pivoted at t upon a support, H. The other end of the bell-crank at s is attached to the hand-connection t, the connection consisting in a cord, chain, or wire extended to a point adjacent to the clock.

A sliding bolt, i, is fitted to guides it upon a bed, I, adjacent to the pulley d, a cord, J, being attached thereto and carried over a pillley, J, so as to be pulled downward by means of a handle, K. The bolt is provided with a notch, 12, and a hinged catch, w, is pivoted upon the bed at w, so as to engage the notch when the handconnection is pulled up to actuate the damper,and the catch is provided with an arm, L, extended transversely to the cord p, to engage a ring, L, attached to the latter.

A spring, N, is applied to the arm 8 of the bell-crank in such manner as to pull upon the hand-connection i when the bolt is sustained by the catch w, and it thus operates when the bolt is released to overcome the inertia or friction of the hand-connection, whatever its length, and to actuate the cord 1* upon the damper. This cord r may be so attached to the damper that the latter shall be either opened or closed when the hand-connection is pulled up and caught; and supposing that the damper has been closed, after the cord 1- is slackened by the pulling of the hand-connection, the operation of the entire construction is as follows, to open the damper automatically at a given time: The handle K having been pulled in opposition to the spring N until the catch w engages the notch in the bolt, as shown in Fig. 1, the disk F is then turned with the proper indication of the dial, as V, under the hour-hand, and then operates to lock the stopwheel in the pulley-train. The cord 1) is then pulled down until the ring L may be slipped over the end of the arm L, as shownin Fig. 1. The stop-wheel being locked, and being connected with the spur-wheel e by the gear f, the detent c prevents any rotation of the pulley under thestrain of thesprin gb until the stop-Wheel is released, and the ring L therefore hangs loosely over the end of the arm L until the rotation of the hour-spindle brings the notch in the disk F opposite the toothlat the appointed time, five o clock. The tooth Z then drops into the notch in the disk, and the pawl 1' falls from the teeth of the stop-wheel, allowing the pulley to rotate without any obstruction in the direction of the arrow d under the influence of the spring b. Such rotation instantly winds up the cord 1), pulling the catch out of the notch in the bolt 15, and permitting the spring N to move the bell-crank and pull the cord r to open the damper. Should the cord be attached to'the damper in the opposite direction, the operation of the mechanism would serve to close the damper at a predetermined time.

It is obvious that the hand-connection may be pulled up and locked at any time, regardless of the connection afforded by the cord 1) with the pulley-train, and as such pulling of the hand-connection operates to slack the cord 7 the damper is then left in such a condition that it may be opened or closed at pleasure, regardless of such cord. The hand'conne'ction may therefore be pulled upland allowed to remain locked at anytime after the pulleytrain has operated.

In whichever way the spring N is intended to actuate the damper, the latter is placed in the opposite position after the hand-connection has been thus pulled up and locked. The cord 1) may then be connected with the arm of the catch w, as described above, and the entire device will be then set for its automatic movement.

The handconnection may in practice be supplied with any number of bell-cranks, and may be carried in any direction and toany distance, and the spring N may be applied at any point in such connection where it will perform the functions described.

In Fig. 4 is shown, however, a hinged draftdoor connected directly to the hand-connection t, and operating by its weight to move the said connection and close the draft-aperture 0* without the use of any actuatingspring, such as is described above. The con struction I have devised for .the clock mechanism, and the locking device for the handconnection, may therefore be used with or without a spring to actuate the damper, or with an equivalent weight.

I am aware that other clock-movements have been provided with attachments to actuate a damper; but I am not aware that any clockmovement has ever been provided with an independent train of wheels actuated by a special spring, and provided with a stop-wheel operating in the manner described herein. .I therefore disclaim other constructions and claim my own invention as described herein, whether the same be applied to a damper for either smoke or cold air, or for opening or closing a hot-air register in a given apartment at a predetermined time.

It is evident that the mechanism I have devised will operate the same, whatever may be attached to the cord t or r, and that either of them may therefore be connectedwith a damper in a hot-air pipe supplying warmth toa single apartment, and actuated so as to open or close such pipe at the desired time. By this arrangement a single room may be warmed in advance of the time for rising from bed in the morning, or for holding a meeting or assem bly, and without the attendance of any operator after the actuating-handle K is pulled. Such handle may be modified in form, or connected with the bolt at a distance, if needful.

I claim herein as follows:

1. In a damper-regulator, the means for uncatching the bolt at a specified time, consisting in the combination,with a clock-movement, of the auxiliary train provided with a pulley, a spring, a stop-wheel, and a pawl controlled by the I clock-movement, substantially as shown and described.
